retrofit - java.lang.NoClassDefFoundError : Failed resolution of: Lokio/Buffer;

Question

当我使用retrofit时，我得到了异常java.lang.NoClassDefFoundError:无法解析:Lokio/Buffer；我使用okhttpclient来设置retrofit的 header 。get userList是一个post方法，我需要发送正文应要求。

private void getUserList(int startIndex){
    final JSONObject audienceObj = ProtocolHelper.getProtocolUtils(mContext).getUserlistJsonObj(mRoomData.mUid, mRoomData.mRoomId, startIndex);
    OkHttpClient okClient = new OkHttpClient.Builder()
    .addInterceptor(
        new Interceptor() {
          @Override
          public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException {
                Request original = chain.request();

                // Request customization: add request headers
                Request.Builder requestBuilder = original.newBuilder()
                        .header("sessionId", CommonData.getUserInfo(mContext).sessionId);
                Request request = requestBuilder.build();
                return chain.proceed(request);
            }
        })
    .build();


    String baseUrl = ProtocolUtils.BASE_URL+"/";
    Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(baseUrl)
    .addConverterFactory(GsonConverterFactory.create())
    .client(okClient)
    .build();

    String audienceUrl = ProtocolHelper.getProtocolUtils(mContext).getProtocolUrl(ProtocolUtils.PROTOCOL_MSG_ID_MEMBER_LIST);
    AudienceInterface audienceInterface = retrofit.create(AudienceInterface.class);
    Call<String> call = audienceInterface.getAudienceList(audienceUrl,audienceObj);
    call.enqueue(new Callback<String>() {
        @Override
        public void onResponse(Call<String> call, Response<String> response) {
            Log.d(TAG, "onResponse");
        }

        @Override
        public void onFailure(Call<String> call, Throwable t) {
            Log.d(TAG, "onFailure"+t.getMessage());
        }
    });
}

public interface AudienceInterface {

@POST("{url}")
Call<String>getAudienceList(@Path("url") String url,@Body JSONObject boder);

}

日志 t.getMessage 为:java.lang.NoClassDefFoundError:解析失败:Lokio/Buffer；

我通过添加解决了这个问题:

implementation 'com.squareup.okio:okio:2.1.0'

在 build.gradle(Module: app) 下的依赖项中。
